JOHN W. OSBORNE, OF WASHINGTON, DISTRICT OF COLUMBIA.

IMPROVEMENT IN SALVES.

Specification forming part of Letters Patent No. 219.364., datedSeptember 9, 1879; application filed January 14, 1879.

To all whom it may concern:

Be it known that 1, JOHN WALTER Os- BORNE, of the city of Washington, inthe District of Columbia, United States of America, have invented anddiscovered a certain new, useful, and Improved Composition for theProtection and Preservation of the Skin, of

which the followingis a specification.

are about one (1) part of eucalyptus-oil to two (2) parts of refinedparaffine; but these proportions may be departed from to some extentwithout injuriously affecting the com pound.

In winter the proportion of eucalyptus-oil to paraffine should besomewhat greater than that above given to obtain the same degree offluidity as in summer, the object being to make the composition justplastic enough to be easily spread in athin-filinon the skin, so thatwhen the volatile oil shall have partially evaporated a continuouscoating of protective elastic material shall remain, sufficient toexclude air an d moisture and defend the skin against all agencies-whichtend to rob it of its suppleness. The union of the eucalyptus-oil andparaffine is effected by the aid of heat.

To the compound so formed a small quantity of white wax may beaddedabout one per centum. This does not affect the preservative andhealing properties of the preparation in any way; but it is useful inhindering a slight tendency which the paraffine possesses to crystallizeout of the solvent and separate from it in part. The presence of the waxcauses the whole to remain homogeneous, and

is therefore serviceable, though not absolutely essential.

This invention is an improvement on my former Patent No. 111,376, of1871, in which I employed the mineral oils as solvents for paraffine;but for medicinal and toilet purposes I find the oil of eucalyptus to bea vast improvement over any mineral ingredient, inasmuch as, in additionto solvent properties of equal efficiency, it has a positive healingaction of its own upon the skin, due to its balsamic properties; and,furthermore, its natural fragrance obviates the need of adding any ofthe essential oils which must be used in conjunction with the productsof petroleum to overcome or disguise their disagreeable odor.

If desired, the perfume of the eucalyptus may, however, be modified tosuit taste or fancy by the addition of any agreeable and non-irritatingperfume.

In cases of chaps, cracks, or roughness of the skin caused by exposureto cold or wet, this compoundisa healing agent of great value, and aprotection against the weather as well, each of its ingredientscontributing to its efiicacy for these purposes.

It is cleanly and non-oleaginou's, and does not soil or injure the mostdelicate clothing, and, by reason of the absence of mineral oil, is

a most valuable toilet articleand remedial preparation for delicate orchapped skin, particularly of ladies or children, or for burns and mostepidermal injuries, while equally as efficient as the former preparationas a protective for the hands of dyers, chemists, photogra pliers, 850.,against acids, alkalies, and other corrosive agents.

I claim- The improved composition herein described, consisting ofeucalyptus oil combined with paraffine, substantially as specified.

JOHN WALTER OSBORNE.
